Abstract Objective Physical training (PT, e.g., Tai Chi and strength training) has been demonstrated to improve balance control and prevent falls. Recently, exergame intervention (EI) has emerged to prevent falls by enhancing both physical and cognitive functions in older adults. Therefore, we aim to quantitatively assess and compare the effects of PT and EI on the performance of balance control and fall prevention in healthy older adults via meta-analysis. Methods A search strategy based on the PICOS principle was used to find the publication in the databases of PubMed, EMBASE, Web of Science, Cochrane Library, and MEDLINE. The quality and risk of bias in the studies were independently assessed by two researchers. Results Twenty studies consisting of 845 participants were included. Results suggested that as compared to PT, EI induced greater improvement in postural control (sway path length, SMD = − 0.66, 95% CI − 0.91 to − 0.41, P < 0.001, I2 = 0%; sway speed, SMD = − 0.49, 95% CI − 0.71 to − 0.27, P < 0.001, I2 = 42%) and dynamic balance (SMD = − 0.19, 95% CI − 0.35 to − 0.03, P = 0.02, I2 = 0%) in healthy older adults. The EI with 90–119 min/week for more than 8-week significantly reduced falls. Subgroup analyses revealed that exergames, which were designed by the two principles of repeatedly performing diversified tasks and gradually increase the difficulty of the task, induced significant effects in improving balance control and falls prevention respectively (P = 0.03, P = 0.009). In addition, intervention that combines EI and PT induced significant improvement in postural control (P = 0.003). Conclusion The exergame intervention, especially the combination of EI and PT, is a promising strategy to improve balance control and reduce falls in healthy older adults. Future studies with rigorous design, larger sample size, and follow-up assessments are needed to further assess the effectiveness of diverse exergame interventions in fall prevention and to quantify the “dose-effect” relationship, as well as the carry-over effect of such intervention, which will ultimately help optimize the rehabilitative strategies to improve balance control and prevent falls.

Abstract Objectives The long-lasting efficacy of working memory (WM) training has been a controversial and still ardently debated issue. In this meta-analysis, the authors explored the long-term effects of WM training in healthy older adults on WM subdomains and abilities outside the WM domain assessed in randomized controlled studies. Method A systematic literature search of PubMed, Web of Science, PsycINFO, Cochrane Library, ProQuest, clinicaltrials.gov, and Google Scholar was conducted. Random-effects models were used to quantitatively synthesize the existing data. Results Twenty-two eligible studies were included in the meta-analysis. The mean participant age ranged from 63.77 to 80.1 years. The meta-synthesized long-term effects on updating were 0.45 (95% confidence interval = 0.253–0.648, &lt;6 months: 0.395, 0.171–0.619, ≥6 months: 0.641, 0.223–1.058), on shifting, 0.447 (0.246–0.648, &lt;6 months: 0.448, 0.146–0.75, ≥6 months: 0.446, 0.176–0.716); on inhibition, 0.387 (0.228–0.547, &lt;6 months: 0.248, 0.013–0.484, ≥6 months: 0.504, 0.288–0.712); on maintenance, 0.486 (0.352–0.62, &lt;6 months: 0.52, 0.279–0.761, ≥6 months: 0.471, 0.31–0.63). Discussion The results showed that WM training exerted robust long-term effects on enhancing the WM system and improving processing speed and reasoning in late adulthood. Future studies are needed to use different tasks of the same WM construct to evaluate the WM training benefits, to adopt more ecological tasks or tasks related to daily life, to improve the external validity of WM training, and to identify the optimal implementation strategy for WM training.

ABSTRACT Protein supplementation is an attractive strategy to prevent loss of muscle mass in older adults. However, it could be counterproductive due to adverse effects on appetite. This systematic review and meta-analysis aimed to determine the effects of protein supplementation on appetite and/or energy intake (EI) in healthy older adults. MEDLINE, The Cochrane Library, CINAHL, and Web of Science were searched up to June 2020. Acute and longitudinal studies in healthy adults ≥60 y of age that reported effects of protein supplementation (through supplements or whole foods) compared with control and/or preintervention (for longitudinal studies) on appetite ratings, appetite-related peptides, and/or EI were included. Random-effects model meta-analysis was performed on EI, with other outcomes qualitatively reviewed. Twenty-two studies (9 acute, 13 longitudinal) were included, involving 857 participants (331 males, 526 females). In acute studies (n = 8), appetite ratings were suppressed in 7 out of 24 protein arms. For acute studies reporting EI (n = 7, n = 22 protein arms), test meal EI was reduced following protein preload compared with control [mean difference (MD): −164 kJ; 95% CI: −299, −29 kJ; P  = 0.02]. However, when energy content of the supplement was accounted for, total EI was greater with protein compared with control (MD: 649 kJ; 95% CI: 438, 861 kJ; P &lt; 0.00001). Longitudinal studies (n = 12 protein arms) showed a higher protein intake (MD: 0.29 g ⋅ kg−1 ⋅ d−1; 95% CI: 0.14, 0.45 g ⋅ kg−1 ⋅ d−1; P &lt; 0.001) and no difference in daily EI between protein and control groups at the end of trials (MD: −54 kJ/d; 95% CI: −300, 193 kJ/d; P  = 0.67). While appetite ratings may be suppressed with acute protein supplementation, there is either a positive effect or no effect on total EI in acute and longitudinal studies, respectively. Therefore, protein supplementation may represent an effective solution to increase protein intakes in healthy older adults without compromising EI through appetite suppression. This trial was registered at PROSPERO as https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42019125771 (CRD42019125771).

AbstractThe literature on repetition priming in Alzheimer’s disease (AD) is inconsistent, with some findings supporting spared priming while others do not. Several factors may explain these inconsistencies, including AD severity (e.g., dementia vs. Mild Cognitive Impairment; MCI) and priming paradigm-related characteristics. This systematic review and meta-analysis provides a quantitative summary of repetition priming in AD. We examined the between-group standard mean difference comparing repetition priming in AD dementia or amnestic MCI (aMCI; presumably due to AD) to controls. Thirty-two studies were selected, including 590 individuals with AD dementia, 267 individuals with amnestic MCI, and 703 controls. Our results indicated that both individuals with aMCI and AD dementia perform worse on repetition priming tasks than cognitively older adults. Paradigm-related moderators suggested that the effect size between studies comparing the combined aMCI or AD dementia group to cognitively healthy older adults was the highest for paradigms that required participants to produce, rather than identify, primes during the test phase. Our results further suggested that priming in AD is impaired for both conceptual and perceptual priming tasks. Lastly, while our results suggested that priming in AD is impaired for priming tasks that require deep processing, we were unable to draw firm conclusions about whether priming is less impaired in aMCI or AD dementia for paradigms that require shallow processing.

IntroductionOlder adults are clinically heterogeneous and are at increased risk of adverse outcomes during hospitalisation due to the presence of multiple comorbid conditions and reduced homoeostatic reserves. Acute geriatric units (AGUs) are units designed with their own physical location and structure, which provide care to older adults during the acute phase of illness and are underpinned by an interdisciplinary comprehensive geriatric assessment model of care. This review aims to update and synthesise the totality of evidence related to the effectiveness of AGU care on clinical and process outcomes among older adults admitted to hospital with acute medical complaints.DesignUpdated systematic review and meta-analysisMethods and analysisMEDLINE, Cumulative Index of Nursing and Allied Health Literature, Controlled Trials in the Cochrane Library and Embase electronic databases will be systematically searched from 2008 to February 2021. Trials with a randomised design that deliver an AGU intervention to older adults admitted to hospital for acute medical complaints will be included. The primary outcome measure will be functional decline at discharge from hospital and at follow-up. Secondary outcomes will include length of stay, cost of index admission, incidence of unscheduled hospital readmission, living at home (the inverse of death or institutionalisation combined; used to describe someone who is in their own home at follow‐up), mortality, cognitive function and patient satisfaction with index admission. Title and abstract screening of studies for full-text extraction will be conducted independently by two authors. The Cochrane risk of bias 2 tool will be used to assess the methodological quality of the included trials. The quality of evidence for outcomes reported will be assessed using the Grading of Recommendations Assessment, Development and Evaluations framework. A pooled meta-analysis will be conducted using Review Manager, depending on the uniformity of the data.Ethics and disseminationFormal ethical approval is not required as all data collected will be secondary data and will be analysed anonymously. The authors will present the findings of the review to a patient and public involvement stakeholder panel of older adults that has been established at the Ageing Research Centre in the University of Limerick. This will enable the views and opinions of older adults to be integrated into the discussion section of the paper.PROSPERO registration numberCRD42021237633.

ObjectivesThis review aimed to identify mechanisms underlying participation in falls prevention interventions, in older adults with cognitive impairment. In particular we studied the role of motivation.DesignA realist review of the literature.Data sourcesEMBASE, MEDLINE, CINAHL, the Cochrane Library, PsycINFO and PEDRO.Eligibility criteriaPublications reporting exercise-based interventions for people with cognitive impairment, including dementia, living in the community.Data extraction and synthesisA ‘rough programme theory’ (a preliminary model of how an intervention works) was developed, tested against findings from the published literature and refined. Data were collected according to elements of the programme theory and not isolated to outcomes. Motivation emerged as a key element, and was prioritised for further study.ResultsAn individual will access mechanisms to support participation when they think that exercise will be beneficial to them. Supportive mechanisms include having a ‘gate-keeper’, such as a carer or therapist, who shares responsibility for the perception of exercise as beneficial. Lack of access to support decreases adherence and participation in exercise. Motivational mechanisms were particularly relevant for older adults with mild-to-moderate dementia, where the exercise intervention was multicomponent, in a preferred setting, at the correct intensity and level of progression, correctly supported and considered, and flexibly delivered.ConclusionMotivation is a key element enabling participation in exercise-based interventions for people with cognitive impairment. Many of the mechanisms identified in this review have parallels in motivational theory. Clinically relevant recommendations were derived and will be used to further develop and test a motivationally considered exercise-based falls intervention for people with mild dementia.PROSPERO registration numberCRD42015030169.

Abstract Background: Falls increase as people age and decrease the quality of life. Even though fall interventions have received great attention, fall incidence rates have still arisen. In order for older adults to reap the benefits of evidence-based fall interventions, a challenge of implementation in the real world and right context must be met. Understanding experiences, facilitators, and barriers of fall prevention among four major ethnic groups in the Unites States could be extremely valuable. Objective: The aim of this study was to describe experiences and highlight facilitators and barriers on fall and fear of falling interventions among ethnically diverse community-dwelling older adults. Methods: Four ethnically specified (African American, Asian, Hispanic and Non-Hispanic White) focus groups were conducted. A total of 28 older adults and four family caregivers were interviewed. Interviews covered experiences on falls and fear of falling, attitudes, factors, consequences, risk assessment, and interventions. Data were organized and analyzed with the NViVo software. Results: Falls related experiences and behaviors were multifaceted and varied. Three themes related to falls experiences and behaviors were identified, 1) falls prevention versus fear of falling amplification; 2) role identity, culture and family considerations; and 3) take care of you, take care of me. Facilitators of fall prevention were integration of individual learning within a group meeting, providing appropriate assistive devices and promoting environmental safety. Barriers were inconsistent fall risk assessments, low fall risk awareness and acknowledgment, and balance and visual impairment.
